In the patch about advanced TDR mode, we force to always set
amdgpu_gpu_recovery=2 under SRIOV. This is not ideal, since we
may want to revert back to use the legacy TDR routine.
Therefore, we only set amdgpu_gpu_recovery=2 when it is
configured as AUTO, which is the default va
drm_gem_object_put calls release_notify callback to free the mem

I suspect it is still needed, especially when amdgpu_ras_fini is used to deal

It's not necessary, because before hw fini, all ras features have been disabled

Good catch. We still need to release ras object in the end. Any reason the

Just a general comment. Could you name the new subdirectory "amdgpu"
instead?
DC is just a component of the amdgpu driver and I think it would sooner
or later make sense to group together the amdgpu documentation in one
